If ever I have issues with my shipment, this company deals with absolute professionalism and swiftness, and I know that they work very hard-even overtime-to accomplish customer satisfaction. Even if you write them a last minute letter (I prefer to write over calling), they acknowledge it and correct it as fast as possible. On a couple of occasions, I had certain issues with my shipment; once I was at fault; once it was a technical issue. They dealt with it in a friendly, efficient manner. I’m always impressed with their cordiality and competence!

I had a rather complicated shipping issue with an order I made for a few Christmas gifts. Mandy helped me solve the issue quickly and to great satisfaction. Therory 11's cards are awesome as well as their customer service.
